Sad Ladies - Please Help

Help! A couple of my ladies are not doing well. First pic is close up of the least happy plant. The second picture shows top down of the unhappy plant (right, “Plant A”) and her quite happy neighbor (left, “Plant B”). So I think environment is able to be ruled out since Plant B is thriving. She’s two and half weeks into flower and starting to stink real good. As succinct as I can:

Plant A: Mimosa autoflower, 3 Gallon fabric pot, Mother Earth Groundswell + 10% homemade compost, pH 6.2 all waterings/feedings, GH FloraTrio nutes (1/2 strength), watering when dry.

Plant B: Royal Gorilla auto, 5 Gallon fabric pot, Happy Frog + 10% homemade compost, pH 6.2 all waterings/feedings, GH FloraTrio nutes (1/2 strength), watering when dry.

So, differences:

  • 3 gal vs. 5 gal
  • Groundswell mix vs. Happy Frog
  • Gorilla sprouted 2 weeks before Mimosa

Confusions:

  1. Do I know what “dry” means? Are we talking when I press a finger in an inch, it is light brown and void of ALL moisture? Not darker and cool when I brush the top dry layer away?
  2. I am waiting for a light to get another tent up and running, so I have a lot packed into that tent. Could it be a CO2 deficiency due to the amount of plants in there now? I have proper air flow with a fan running 24/7.


Hey @ijsommer , welcome to the forum.
Its not CO2, that is always abundant unless they are locked in a completely sealed room for a long time.
What you might have is hydrophobic soil. Some soils will get so dry on top that they repel water and it just runs down the sides and never actually wets the dirt. Give it a little water and watch if it sets on top for a short time. TO fix it you can give a little water at a time and let it soak in and then more and so on. Look up Hydrophobic Soils on YouTube for more info.
Thats my best guess.

Easy way to determine dry is to lift the bags slightly and feel if its light or heavy.

Thanks @Spiney_norman , it isn’t hydrophobic soil, I have dealt with that on other houseplants. The plant never had any issue taking water. I’m leaning overwatering but I thought I was being careful.

Not only lifting but I’ve also gone by if the leaves only are drooping it’s thirsty if leaves and stems are both drooping it’s over watered

Indoors I use these and I’m trying to figure out a way to make my own outdoors

It’s the easy way out but I’m literally doing jumping jacks over my plants

Mind the ugly fabric pots lol they are on their third cycle with just tilling and replenishing
I’m prob going to try washing machine and outdoors only from now on ,
Going to actually brand new every indoor grow

However and this should be obvious
A plant completely starved of water will also collapse like on a hot day and look life less but the obvious art should be that it weighs nothing and all dried up

She looks thirsty in the pictures. I would water and see if she’s awake in the morning. They sure can drink a lot. If the soil is dry or at least the top inch or two she’s thirsty. I would like to follow this post if you would update tomorrow. Happy growing

Let her dry out a lot so the pots light and she is showing she wants a drink.
It’s that or a root issue.
I’ve seen that look before on several plants in the past and they were dead in a day or two due to root issues. It amazed me at the speed that it happened.

Let’s hope it’s just too wet at the moment.
It’s in a 3 gallon pot so I would think you give less water than the one in the 5 gallon.
Lift the pots before and after watering. You can lift the entire pot or just grip the edge and lift up one side and after doing this several cycles you’ll have a better feel of where things are at in seconds.
The 5 gallon looks great
Hope you get this sorted out

Exactly what I do outside where we can’t control and predict conditions
I would live to come up with some type of self watering system outside not necessarily bottom feeding but that would be cool also

Yeah @Skydiver they are definitely overwatered. I am currently letting them dry to the point of showing. I do give less water to the 3 than the 5. And yes, very much hoping that it dries out and recovers, don’t want to lose plants…

Here is a video I found that explained it pretty well.

Overwatering vs underwatering

I would purchase the Ac infinity self watering bases with some fabric pots for your next grow. That way you can’t over water or under water. My plants drink about a gallon or more per day at that stage.

Agreed that’s what I use they are great
